Biological fertilizers are among natural components which can be uses as supplement or alternative to chemical fertilizers in sustainable agriculture. The effects of triple super phosphate fertilizer and biological phosphate fertilizer (fertile 2) on distribution of dry matter and grain yield of Maize Single Cross 704 were examined in 2012 in Shahid Salemi Field in Ahvaz as a factorial experiment in the form of randomized complete block design with four replications. The experiment included two factors: first, biological phosphate fertilizer (fertile 2) at three levels of 0, 100, 200 g/ha; second, triple super phosphate chemical fertilizer at three levels of 0, 60, 90 kg/ha of pure phosphorus (P2O5). The obtained results indicated the increase of grain yield, leaf dry weight, stem dry weight, maize cob dry weight, tassel dry weight and total weight of maize in treatments with integration of phosphate bio-fertilizer (fertile 2) and triple super phosphate chemical fertilizer. P2B2 treatment (100 g/ha biological phosphate fertilizer (fertile 2) and 60 kg/ha triple super phosphate fertilizer) had the highest biological yield and grain yield. Generally, it could be said that the increase of yield and elements uptake by the plant is related to the increase of soluble phosphorus in soil so that phosphorus plays an important role in root development and prevention of the accumulation of phosphorus compounds and their negative effects on the absorption of some elements by the soil. With regard to the results obtained it seems like that the decrease of application of triple super phosphate chemical fertilizer to less than a half together with the use of biological phosphate fertilizer (fertile 2) is particularly important to achieve more grain yield in Ahvaz weather conditions. The results showed that phosphate (fertile 2) significantly increased the grain yield, leaf dry weight and stem dry weight.
